Abstract

Process for control and regulation of the interpole distance and the alumina concentration in electrolytic cells for the manufacture of primary aluminium. The process according to the invention comprises control of the concentration by weight of alumina in the cryolite bath above values lying around 2%, which correspond to the maximum current efficiency.
